Definitions

  • this invention relates to needle shields for protecting the user of a needle from needle stick. More particularly, this invention relates to needle shields of the kind used with medical applications so that the shield moves in place for protecting the user from needle stick and potential contamination from a used needle.
  • U.S. Pat. No. 4,659,330 includes a mounting arrangement for mounting on a syringe body with the device including a hinge connection for swinging a needle shield into place over a contaminated needle once it has been used.
  • a simplified arrangement of needle shield is provided with a press-fit mounting which may be secured to the needle hub of either a syringe barrel or a blood sample needle holder for taking blood samples.
  • the arrangement herein may be frictionally positioned and press fitted onto such a hub. When so positioned, the arrangement herein moves into place automatically for shielding the needle prior to use, and at all other times except during the time when the needle is actually inserted into a patient.
  • the arrangement here includes a flexible elongated integral device which extends over and along the needle top and both sides thereof with a hood shield at one end for extending over the point of the needle.
  • the blunt hood shield at the front end is pressed against the skin of a patient and the needle inserted into the patient for administering a medication, or for removing a blood sample for examination.
  • the shield of the invention moves automatically, with no manipulation required by the user, back into place over the point of the needle so that the user is immediately and automatically protected from any kind of accidental needle prick.
  • the used needle therefore, may be readily moved to a disposal container for removing the needle and the shield of the invention by dropping them into the container, while the point of the needle is maintained in a protected shielded manner.
  • the needle shield assembly of the invention includes a frictional locking arrangement which the user may utilize for pressing the shield of the invention over the needle for holding the shield firmly in place over the needle when it is not being used, before or after contamination.
  • needle shield taught herein may be comprised of an inexpensive single piece of flexible plastic produced on a mass production basis, making it inexpensive for single use applications.
  • FIG. 1 is a top plan view of the assembly of the invention fixed to the hub of a conventional blood sample needle holder;
  • FIG. 2 is a top plan view of an additional embodiment of the assembly of the invention, also fixed to the hub of a conventional blood sample needle holder;
  • FIG. 3 is a longitudinal side elevational view of the embodiment of FIG. 1;
  • FIG. 4 is a view of the device in FIG. 3, reduced in size, and shown in the position immediately prior to the use thereof when a needle is being positioned for insertion into the skin of a patient;
  • FIG. 5 is a view of the assembly of FIG. 4 in a subsequent position wherein the needle is inserted into the skin of a patient;
  • FIG. 6 is a longitudinal side elevational view of the assemblies of FIGS. 3, 4 and 5 shown after use of the needle wherein the flexible needle shield of the invention is being press fit by the user over the contaminated needle;
  • FIG. 7 is a sectional view taken along lines 7--7 of FIG. 3.
  • FIG. 1 shows the needle shieldassembly 10 of the invention fitted on the hub 16 of the neck 15 of a conventional blood sample needle holder 12.
  • Needle holder 12 includes a finger grip arrangement 14 in the usual manner.
  • One end 17 of the flexibleneedle shield body 18 is press fit onto hub 16, while the opposite end 20 thereof is in the form of a needle point hood 20.
  • the longitudinal flexible body 18 forming the shield of the invention includesthe flexible mounting grip or holder 17 which is press fit over hub 16 of holder 12.
  • Mounting grip or holder 17 may be a partial ring which is snapped over hub 16, or a full ring which is slipped over hub 16 and, because of its flexible properties, pressed onto hub 16 in a frictional engagement.
  • Hub 16 holds, in the usual manner, a needle 36 for insertion into a patient.
  • the opposite end of shield 18 includes the blunt front end hood 20 which hangs over point 48 of needle 36.
  • assembly 10 may include a frictional locking guard 38 which depends from the flexible body 18 for gripping the needle and holding the flexible hood-like body 18 suspended over needle 36, once contamination of needle 36 has taken place.
  • the assembly 10 is shown in a position prior to the point 48 of needle 36 being inserted into the skin 44 of a patient.
  • the blunt front end hood 20 is resting against the patient's skin prior to any application of force by the technician for inserting needle 36 into the skin of a patient.
  • the needle is moved in the direction of arrow 52 so that point 48 of needle 36 enters skin 44 of a patient.
  • the flexible elongated body 18 is flexed in the direction of arrow 50 so that the needle guard or holder 38 slips off of needle 36.
  • the flexible properties of the body 18 of the needleshield of the invention causes the shield to move back over the needle 36 for protecting the user from contamination.
  • the hooded curvature of the arrangement shown protects the user over the top of the elongated needle body as well as the point 48 thereof.
  • the blunt front end of hood 20 moves in the direction of arrow 58 downwardly, as shown in FIG. 6 so as to protect the user from contaminated point 48.
  • This allows single-handed maneuvering by the user.
  • the assembly includes a snap-lock guard pressure by thefinger 54 of the user moving in the direction of arrow 56 causes guard 38 to snap over the needle body 36 and hold the shield in place until such time as the entire assembly, including the shield and needle are removed from the hub 16 of holder 12, and dropped into a container for contaminated needles.
  • the needle shield body is in the form of two elongated flexible side parts 28 extending along the side of a needle 32. These two side portions or halves 28 are a substitutefor the flexible body 18 shown in the embodiment in FIG. 1.
  • the assembly 21 includes a front end hood 30 extending over the point 33 of needle 32, while the opposite end of the assembly includes a flared gripping ring arrangement for gripping hub 26 positioned on neck 25 of a holder 22, in the same manner as the embodiment shown in FIG. 1.
  • the assembly 21 may also include a snap guard 34 in the same manner as guard 38 in the FIG. 1 arrangement for gripping needle 32.
  • the arrangement21 shown in FIG. 2 is arranged so that the user may observe the position ofthe needle 32 from the top prior to and during use, when it is inserted into the skin of a patient.
  • FIG. 7 shows a sectional view of the assembly in FIG. 3 taken along lines 7--7 of FIG. 3 and shows the arrangement of parts including the frictional gripping arrangement or guard 38 which depends from and is integral with elongated flexible shield body 18.
  • the snap lock arrangement 38 depends in a u-shaped form with a small opening at thebottom thereof for allowing passage of needle 36 therethrough.
  • this invention a simple, inexpensive device for protecting the user ofneedles in medical applications from contamination brought on by accidentalprick from such contaminated needles.
  • the arrangement of the invention is so simple in its construction that it can be made in great quantities and thrown away after use with its associated needle.
  • the arrangement may be made by simple molding operations of a variety of thermoplastic materials which provide the flexibility necessary to impart the desired flexible property during use of the needle shield of the invention.
  • this simplified arrangement herein may be comprised of a single piece of inexpensive plastic material which may be produced on a production line basis. Materials are selected which provide the degree of flexibility required for the purposes of the use of the invention herein.
  • the elongated body arrangement of the invention herein may be modified as long as it retains its flexible properties and allows for movement of the front end hood of the needle shield of the invention away from the needle during use while allowing for immediate automatic spring-back to the original position protecting the user from the point of the contaminated needle.
